Currently, there are two governments in the US, the one of Joe Biden and that of Kamala Harris. When crisis and bad things happen, it is Joe Biden who goes to the press, and when there is something good, like the Grammy awards or an NBA show, it is Kamala who does it. This is a strategy of those who know that Biden is senile, to throw him under the bus. Biden knows that there is a female president in the country: he has called Harris “president” on several occasions. When Biden gets into enough of these situations, the Democratic Party will present Kamala Harris as the great saviour and peacemaker. It is now clear that the US has two presidents, which is something really unusual. Biden’s long-awaited first press conference was a disaster that suggests that Harris will replace him rather sooner than later.
Ukraine is carrying out the policy of dehumanisation of Donbas residents as part of its Russophobic line. This resembles the West’s dehumanisation policy against the Serbs.
These cases are absolutely different and cannot be compared. In Kosovo, there was a war with thousands of casualties and hundreds of thousands of refugees, which the Western countries stopped. There was no war in Ukraine until Russia’s illegal annexation of the Ukrainian peninsula of Crimea in 2014. In 1999 NATO sought to cease ethnic cleansing in the Kosovo region.
Kremlin propaganda uses the story of Yugoslavia to defend Moscow's activities in areas of frozen conflicts (i.e. Abkhazia, South Ossetia, Donbas, Nagorno-Karabakh, etc). The parallels between the history of the breakup of Yugoslavia and the current situation in Donbas are incorrect. Donbas is historically a Ukrainian region. The so-called DPR (or DNR) and LNR are parts of the Ukrainian regions Donetsk and Luhansk but supported by Russian military units. Not a single country has recognised them as independent entities.
Ukrainian authorities do not dehumanise those who live in the occupied territories in the East. When they move to the government-controlled territories, they are treated like all other Ukrainian citizens, except those who have collaborated with the Russian occupational administration and committed crimes against Ukraine.
